Question 10

Natural gas is a non-renewable energy source.

Natural gas is classified as a non-renewable energy source because it is derived from fossil fuels, which are formed over millions of years from the remains of ancient organisms. Once extracted and used, this resource cannot be replenished on a human timescale.

A) Geothermal

Geothermal energy is renewable as it harnesses heat from the Earth's interior, which is continuously replenished. The sustainable nature of geothermal energy makes it an environmentally friendly alternative to fossil fuels.

B) Solar

Solar energy is also a renewable resource. It is derived from sunlight, which is abundant and inexhaustible on a human timescale. This energy can be harnessed through various technologies such as solar panels.

C) Natural gas

Natural gas is indeed a non-renewable energy source, as it is extracted from the earth and takes millions of years to form. Once used, it cannot be replenished in a short time frame, making it unsustainable in the long run.

D) Hydroelectric

Hydroelectric energy is considered a renewable resource because it utilizes the flow of water to generate electricity. As long as water cycles continue, this energy source can be harnessed repeatedly without depleting it.

Conclusion

Natural gas stands out as the non-renewable energy source among the options provided due to its finite nature and the long time required for its formation. In contrast, geothermal, solar, and hydroelectric energies are sustainable and can be continuously harnessed without depleting their resources. This distinction is crucial in discussions about sustainable energy practices and the transition away from fossil fuels.
